He got a 5% raise, so 28,140 is 105% of what it used to be.
105% means 1.05
(1.05) x (salary before increase) = 28,140
Divide each side by 1.05 :
Salary before increase = 28,140 / 1.05 = <u>26,800</u> .
The rest of the question is nonsense. The salary
before increase IS last year's salary.

Greetings from Brasil...
Here we don't have much to go
∛Y = A.(C + 1/X)
∛Y = (AC + A/X)
raising both members to the cube.....
(∛Y)³ = (AC + A/X)³
from Notable Products: (a + b)³ = a³ + 3a²b + 3ab² + b³
Y = (AC)³ + 3(AC)².(A/X) + 3AC(A/X)² + (A/X)³
Y = A³[C³ + (3C²/X) + (3C/X²) + (1/X³)]
